OIL STOVE Fil ed June so, 1928 Dec. 2, 1930 PANT GLOW OIL BURNER CORPORATION, OF HARTFORD,

OF CONNECTICUT Application filed June 30,

t ployed for various purposes, as for heating water, for cooking etc, which stove or heater shall be of simple construction and particularly eihcient in operation.

, One form of stove embodying the inven t tion and in the construction and use of which the objects herein set'out, as well as others,

may be attained, is illustrated in the accompanying drawings, in which Figure 1 is a view in elevation of a stove 15 embodying my invention.

Figure 2 is a top view of the same. Figure 3 is a View, scale enlarged, in central vertical section through the stove.

In the accompanying drawings the numeral 5 indicates the jacket or shell of my improved stove that may be of any suitable construction and the walls of which may be insulated", if desired, as by placing an insulatin mate rial between an outer and an inner s ell, as

5 shown in Figure 3 of the drawings, and this construction may apply to the bottom as well as the sides. This stove may be supported as upon legs 6 and a tank 7 for the fuel may be located at one side of the stove and resting 30 upon a distributor 8 from which a supply pipe 9 extends to the burner within the stove, said supply pipe extending upw ardly through the bottom of the stove.

The heater comprises a base 10 resting upon 35 the bottom of the jacket 5 and with an outer shell 11 resting upon a shoulder on said base at the side of a flange 12. The base has arim 13 that rests upon the bottom of the jacket and a hub 14 at its center also resting upon W said bottom and with openings 15 through the bottom of said base, which bottom is located above the edge of the rim 13. A support 16 of tubular construction rests upon and rises from the bottom of said base to sup.-

port a burner base 17 a bolt 18 passin downwardly through the burner base 17, t e support 16, the hub 14 and the bottom of the jacket, as shown in Figure 3.

Grooves -19 and 20 are concentrically ar- 0 ranged in the burner base with shoulders at purposes.

the mouth of said grooves upon which shoulders burner shells 21-2223-24 rest, this providing two burner fiues 2526 with an air space 27' between them. The supply pipe 9 delivers into the bottom of the groove 19 and a port 28 extends from this groove to the burner groove 20. These shells 2122-23 24 are perforated in a manner common to burners of this class, the central opening 29 being closed by a cap 30 and the space between the two burner flues being closed at its upper end. Holes 31 extend through the burner base and air is supplied as through holes 32 in the jacket 5, through openings 33 in the rim of the base 10 and through the holes 1.5 and 31 and from thence through the perforations in the shells 21222324;

A coil 34 of pipe is located within the outer shell 11, encircling the burner as a whole including the burner shells, this coil having ends 35 extending through thejacket 5 and intended for connection to a tank or reservoir for holding a liquid to be used for heating A top 36 is placed upon the upper edge of the jacket 5, and this top has an opening that maybe closed by a cross piece 37 and covers 38 in a manner commonto stoves employed for cooking purposes.

My improved device comprises not only a structure that may be used in the ordinary manner for cooking purposes, but it also embodies means for heating water, a single vburner being employed for this double purpose and being so arranged as to provide a very compact device and without increasing the size of the structure over what would be required were it employed for ordinary cooking purposes.

The perforations in the shells 2122-23 24 have not been shown herein, but being of old. and well known construction their arrangement will be well understood by a mere reference to them.

In accordance with the provisions of the patent statutes I have described the principles of operation of my invention, together with the device which I now consider to represent the best embodiment thereof; but ,I desire to have it understood that the device lid shown is only illustrative and that the in-,

vention may be carried out by other means and applied to uses other than those above set out.

I claim- 1. A heater comprising a jacket with a cooking top on which cooking utensils are adapted to be placed, a shell within the jacket, a burner within the shell comprising annular fiue walls, means for supplying fuel to the burner, a coil surrounding said burner and disposed outwardly of the flue walls and within the shell and having means for supply of liquid to and discharge of liquid from said coil, said top having an opening overlying said shell and burner, and means for closing said openin 2. A heater comprising a jacket with a cooking top on which cooking utensils are adapted to be placed, a shell within the jacket, a burner within the shell, means for supplying fuel to the burner, a coil surrounding said burner and disposed outwardly of the burner flame area and within the shell and having means for supply of liquid to and discharge of liquid from said coil, means, for supplying air to said jacket and within said shell, said stop having an opening overlying said shell and burner, and means for closing said openin 3. A heater comprising a jacket with a cooking top on which cooking utensils are adapted to be placed, a heater base located within the jacket, a burner base supported by said heater base, means for securing both of said bases together and to the bottom of said jacket, a shell resting on said heater base, a burner within said shell comprising annular flue walls, means for supplying fuel to said burner, a coil surrounding said burner and disposed outwardly of the burner flame area and within the shell and having means for supply of liquid to and discharge of liquid from said coil, means for supplying air to said jacket and within said shell and therefrom to saidburner, said top having an opening overlying said shell and burner, and means for closing said opening.

4. A heater comprising a jacket with a cooking top on which cooking utensils are adapted to be placed, a heater base located within said; jacket and having a rim with an opening through said rim and base to the upper side of the latter, shell seated onsaid heater base, a burner within said shell comprising annular flue walls, means for supplying fucl to said burner, means for supplying air within said jacket, a coil surrounding said burner and disposed outwardly of the flue walls and within the shell and having means for supplying liquid to and for discharging liquid from said coil, said top having an opening overlying said shell and burner, and means to closing said opening.

5. A heater compa casing having bottom and sides and a cooking top on. which. cooking utensils are adapted to be placed, a liquid fuel burner comprising a burner-base secured to the bottom and having an an nular, burner groove formed therein, means for delivering liquid fuel to the burner groove, concentric, perforated, burner shells mounted on said base, to provide between them an annular combustion chamber above the groove having an annular discharge opening at the top for the discharge of the products of combustion beneath the cooking top, a coil. surrounding the outer burner shell and having convolutions extending above the top thereof but outside the area of the annular discharge opening, means for supply ing liquid to the coil and discharging the same therefrom, and a shell surrounding said coil and extending above the top thereof and having an open, upper end to permit the discharge of the products of combustion, said cooking top having an opening ovcrl lllx, said shell and burner and a closure for said opening.
